[0030] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0032] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] The stator winding is the core component of the stator section in an electric motor (including electric motors and generators), and it plays a crucial role in the motor. Its core function can be summarized as: generating the main magnetic field (rotating magnetic field or stationary magnetic field) required for the motor to operate.

[0035] The stator core production process of stator winding involves precision stamping, lamination, heat treatment and insulation treatment. After initial forming, its end face is not flat, and after winding, the wire bundle is relatively messy. The stator winding needs to be placed on a leveling device for leveling.

[0036] The existing leveling operation involves many steps. After the stator core is wound, it is transported by a robot. The end face leveling and wire harness leveling are then carried out. In this process, the robot only has a transport function, and the production efficiency of the stator winding needs to be improved.

[0037] To reduce the number of processing steps for stator windings and improve production efficiency, an embodiment of the first aspect of this utility model provides a conveying device that can convey stator windings via a conveying robot. During the clamping process, the device can flatten the stator core end face of the stator windings and the portion of the stator winding wires protruding from the stator core. Example

[0038] This embodiment provides a conveying device for conveying stator windings.

[0039] Reference Figure 1 and Figure 2 As shown, the stator winding conveying device includes a moving component 2 and a clamping component 1. The moving component 2 is used to drive the clamping component 1 to move (in the horizontal and vertical directions), and the clamping component 1 is used to clamp the stator winding and flatten the wire bundle of the stator winding.

[0040] For example, the stator winding is placed at the processing station by a person or another robot. The moving component 2 drives the clamping component 1 above the processing station, and then drives the clamping component 1 to fall towards the processing station. After reaching the position of the stator winding, the clamping component 1 retracts to surround the outside of the stator winding, and then applies force inward to squeeze the stator winding, thereby flattening the end face of the stator winding and the wire harness. The details are explained below.

[0041] 1. Mobile component

[0042] Reference Figure 1 and Figure 2 As shown, the moving component 2 includes a horizontal linear mechanism 200, a vertical linear mechanism 210, a first mounting plate 3, and a second mounting plate 4. Both the horizontal linear mechanism 200 and the vertical linear mechanism 210 are linear modules. The first mounting plate 3 is disposed at the output end of the horizontal linear mechanism 200, the vertical linear mechanism 210 is disposed at the first mounting plate 3, and the second mounting plate 4 is disposed at the output end of the vertical linear mechanism 210.

[0043] Understandably, the first mounting plate 3 can move horizontally under the drive of the horizontal linear mechanism 200, and the vertical linear mechanism 210 follows the horizontal movement of the first mounting plate 3, that is, the second mounting plate 4 moves horizontally. The second mounting plate 4 can also move vertically under the drive of the vertical linear mechanism 210, and the second mounting plate 4 can move to any position in the vertical plane (within the stroke range of the moving component 2). Since the clamping component 1 is set on the second mounting plate, the position adjustment of the clamping component 1 in the vertical plane can be realized.

[0044] When the horizontal linear mechanism 200 and the vertical linear mechanism 210 work synchronously, the clamping component 1 moves obliquely; when the two work simultaneously and have a certain speed difference, the clamping component 1 moves along an arc trajectory.

[0045] The combined design of the horizontal linear mechanism 200 and the vertical linear mechanism 210 is simple in structure, easy to maintain, and has a lower cost compared to traditional multidimensional robotic arms.

[0046] It should be noted that in some embodiments, the driving forms of the horizontal linear mechanism 200 and the vertical linear mechanism 210 may be the same or different, such as screw driving form, cylinder driving form, etc., which are selected according to actual design requirements.

[0047] Reference Figure 1 and Figure 2 As shown, the horizontal linear mechanism 200 includes two columns 201. The bottom end of each column 201 is provided with a fixed base 202, which fixes it to the frame of the integrated equipment or the ground. Each column 201 is equipped with an adjusting seat 203, allowing adjustment of its position. A horizontal plate connects the two adjusting seats 203, and the height of the horizontal plate can be adjusted via the adjusting seats 203.

[0048] Understandably, the components or structures used to limit the adjustment seat 203 can be bolts, pins, etc. The adjustment seat 203 is locked by bolts, pins, etc., to fix it relative to the column 201, thereby improving the stability of equipment operation.

[0049] It should be noted that in some embodiments, the number of columns 201 can be multiple, and the selection can be made according to actual design requirements, and there is no limitation here.

[0050] Reference Figure 1 and Figure 2 As shown, the horizontal linear mechanism 200 in this embodiment uses a lead screw drive. The horizontal linear mechanism 200 also includes a motor 204, a guide rail 205, a screw 206, and a slide 207.

[0051] Reference Figure 1 and Figure 2 As shown, the guide rail 205 is horizontally mounted on the horizontal plate, the motor 204 is mounted at one end of the guide rail 205, the screw 206 is mounted inside the guide rail 205 and connected to the output end of the motor 204, and a nut is mounted inside the slide block 207, which is fitted onto the screw 206. When the motor 204 starts, the screw 206 rotates, driving the nut to move, thereby driving the slide block 207 to move along the length of the guide rail 205.

[0052] Understandably, the guide rail 205 is provided with multiple guide grooves, and correspondingly, the first mounting plate 3 is provided with protrusions extending into the guide grooves to make the movement of the first mounting plate 4 more stable.

[0053] It should be noted that in some embodiments, the movable connection between the guide rail 205 and the second mounting plate 4 can also be in other forms. For example, the edge of the second mounting plate 4 is provided with a bent hook-shaped structure, which locks the guide groove of the guide rail.

[0054] Reference Figure 1 and Figure 2 As shown, the guide rail 205 is equipped with two photoelectric sensors 208, one located at the starting position of the slide 207 and the other located at the ending position of the slide 207, in order to limit the stroke of the slide 207.

[0055] It should be noted that in some embodiments, the photoelectric sensor 208 can be replaced with an infrared sensor or the like that has the same function.

[0056] Reference Figure 1 and Figure 2 As shown, the first mounting plate 3 is connected to the slide 207 and can move with the slide 207. The first mounting plate 3 is located on the outside of the guide rail 205 and is arranged in the vertical direction.

[0057] It should be noted that in some embodiments, the first mounting plate 3 can be a single piece of plate, or it can be composed of multiple plates spliced ​​together, or it can be a hollow structure.

[0058] Reference Figure 1 and Figure 2 As shown, the vertical linear mechanism 210 includes a linear cylinder 211, a bracket 212, a guide rod 213, and a guide sleeve 214.

[0059] A bracket 212 is mounted on the first mounting plate 3. A linear cylinder 211 is mounted vertically on the bracket 212, and the push rod of the linear cylinder 211 can extend through the bracket 212 to the lower end of the bracket 212. A second mounting plate 4 is connected to the push rod of the linear cylinder 211, and a clamping assembly is located below the second mounting plate 4.

[0060] The guide rod 213 is mounted on the second mounting plate 4, and the guide sleeve 214 is mounted on the bracket 212. The guide rod 213 passes through the guide sleeve 214 to achieve the limiting and guiding function.

[0061] Understandably, the guide sleeve 214 improves the stability of the guide rod 213's movement. Since the guide rod 213 passes through the bracket 212, meaning the hole in the bracket 212 also guides the guide rod 213, the guide sleeve 214 can be removed accordingly. Whether to remove it or not depends on the actual needs.

[0062] It should be noted that in some embodiments, the horizontal linear mechanism 200 can also be a belt-driven or cylinder-driven mechanism. Similarly, the vertical linear mechanism 210 can be a lead screw-driven or belt-driven mechanism.

[0063] 2. Clamping components

[0064] Reference Figure 1 and Figure 3 As shown, the clamping assembly 1 includes a gripper cylinder 10, a slider 11, and a clamping block 12. The slider 11 is located at the output end of the gripper cylinder 10, and the clamping block 12 is located on the slider 11 and can move with the slider 11.

[0065] It is understandable that the output end of the gripper cylinder 10 can be either horizontal or oblique.

[0066] Reference Figure 1 and Figure 3 As shown, the gripper cylinder 10 is a three-grip cylinder 10, and the slider 11 is connected to the output end of the three-grip cylinder 10. The three-grip cylinder 10 is provided with a sliding groove, and the slider 11 is embedded in the sliding groove.

[0067] Three sliders 11 are arranged circumferentially around the center of the three-jaw cylinder 10. The three sliders 11 can move towards the center or away from the center. After the three sliders 11 abut against each other in pairs, they form a ring structure that can surround the stator winding.

[0068] The number of clamping blocks 12 corresponds to the number of sliders 11. The clamping blocks 12 are set on the sliders 11, and the clamping blocks 12 can also form a ring structure that can surround the stator winding.

[0069] The clamp 12 is provided with a wire pushing component 13. The wire pushing component 13 can be detachably provided with the clamp 12, or it can be designed as an integral part of the clamp 12.

[0070] In this embodiment, the slider 11 is provided with a groove for mounting the wire pushing component 13. The wire pushing component 13 is located inside the clamping block 12. The wire pushing component 13 protrudes inward (i.e. towards the center position of the clamping cylinder 10) and can abut against the wire harness at the end of the stator winding to flatten the wire harness.

[0071] The inner side of the pusher component 13 is also provided with a receiving groove 14, which is used to receive the end of the wire harness. When the pusher component 13 flattens the wire harness, the end of the wire harness is not flattened, which facilitates the subsequent assembly and processing of the stator winding.

[0072] Furthermore, the receiving groove 14 is an inclined groove, the length direction of the inclined groove is parallel to the vertical direction, and the depth direction of the inclined groove has an angle with the moving direction of the clamping block 12, so that the end of the wire harness is bent obliquely.

[0073] In addition, the inner wall of the clamp 12 is provided with a contour part 15, which corresponds to the shape of the outer wall of the stator core of the stator winding, so that the clamp 12 fits with the outer wall of the stator core, making it convenient to level the stator winding.

[0074] Understandably, the structure of the contour section 15 is designed based on the shape of the outer wall of the stator core. When different stator windings need to be processed, the clamp 12 can be replaced.

[0075] It should be noted that in some embodiments, the gripper cylinder 10 may have two or more grippers.

[0076] The above description is only a preferred embodiment of this embodiment and is not intended to limit this embodiment. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this embodiment should be included within the protection scope of this embodiment.
